WASTEWATER TREATMENT

The Rio Grande River and the two major aquifers in the El Paso, TX, area had been dried up for decades when El Paso Water Utilities (EPWU) developed the Fred Hervey Water Reclamation Plant, the nation’s first full-scale wastewater reclamation plant to use tertiary treatment to restore wastewater to national and state potable water standards.

WASTEWATER TREATMENT CASE STUDIES AND WHITE PAPERS

The Rio Grande River and the two major aquifers in the El Paso, TX, area had been dried up for decades when El Paso Water Utilities (EPWU) developed the Fred Hervey Water Reclamation Plant, the nation’s first full-scale wastewater reclamation plant to use tertiary treatment to restore wastewater to national and state potable water standards.

A water reclamation facility needed to improve their biosolids handling process in their planned expansion. The solution needed to reduce sludge volume, produce reusable material, be simple to maintain, and provide cost effective operation.

Until the last decade, bromate was seldom a topic of concern for most treatment facilities. However, an increasing shift toward ozone-based disinfection processes has raised awareness of bromide concentrations in raw water and the potential to form bromate through the disinfection process.

When we humans look at objects we describe them in terms of color. We say that an apple is red or a leaf is green. To us color is an attribute just as surely as the mass or dimensions of an object. But the fact is that color is a pure human construct. Take away the human and it does not exist.

The oil and gas industry has utilized various deaeration technologies for many years to remove dissolved gases, particularly oxygen, from injection water. Minimizing the environmental impact, improving operating efficiency, avoiding process issues and protecting system components are just a few of the reasons degassing is necessary in many hydrocarbon recovery and water processes.

Wastewater can be defined and handled in any number of ways, from industrial process water slated for return to the environment, to reclaimed irrigation tailwater used to water crops downstream, to state-of-the-art toilet-to-tap projects. By Amiad Water Systems

Article: A Field Testing Must Have Device
To take control of our water quality, we first need to know what's in
our water. Having portable testing devices to measure important
water quality parameters in the field empowers water treatment
professionals with improved water quality understanding, enabling
them to take more immediate and effective action. By Real Tech Inc.

For an open-pit taconite mining operation in Minnesota, high pH groundwater required round-the-clock pumping to comply with discharge permit limits. After management installed a control system to neutralize the pH, the treated water leaving the site now meets permit limits. Read this case study to learn more about the installed system and results.

WASTEWATER TREATMENT APPLICATION NOTES

Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.

One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

Choosing ABS as a partner for dewatering will bring you much more than just the right pump. Our dewatering philosophy is to provide you with the best total combination of expert advice, purchase or rental contract and service support for each specific situation or demand.

The Accelapak is a modular plant combining all the necessary components for clarification, softening, and filtration into a single compact system. Its versatile design makes it ideal for:
Industrial or municipal, potable and service water treatment of well, surface, or water reuse supplies for industrial and municipal applications.

LATEST INSIGHTS ON WASTEWATER TREATMENT

Grit settling velocity is significantly impacted by variability in size, density and shape. The conventional assumption of spheres with a specific gravity of 2.65 is inadequate for characterizing grit.

The impact of preliminary treatment (i.e., grit removal, screening, washing compacting of screenings, handling of screenings, and resource recovery) on downstream processes is becoming more apparent as the industry looks for ways to reduce operating costs and increase process results.
